TREM-2 Lentiviral Activation Particles (h) | sc-401585-LAC | 200 µl | $455.00 |
TREM2 encodes triggering receptor expressed on myeloid cells 2 (TREM-2), a cell-surface immunoreceptor predominantly expressed by microglia, macrophages, and other myeloid lineages. Through association with the TYROBP/DAP12 adaptor, TREM-2 engages ITAM-dependent signaling to modulate SYK–PI3K/AKT and MAPK pathways, coordinating phagocytosis, lipid sensing, chemotaxis, and survival programs. TREM-2 activity shapes innate immune responses and cellular clearance of apoptotic debris and aggregated material, influencing tissue homeostasis under inflammatory stress. Genetic and functional perturbations of TREM2 have been linked to altered microglial states and neuroinflammatory mechanisms relevant to neurodegeneration, including Alzheimer’s disease and related dementias.
TREM-2 Lentiviral Activation Particles (h) address this need by packaging the complete synergistic activation mediator (SAM) transcriptional activation system into transduction-ready, high-titer lentiviral particles, enabling efficient TREM2 upregulation across a broader range of human cell types.
TREM-2 Lentiviral Activation Particles (h) deliver all functional components of the synergistic activation mediator (SAM) system via lentiviral transduction. The system comprises three particle preparations co-transduced into target cells: one encoding catalytically inactive dCas9 (D10A and N863A mutations) fused to the VP64 transactivation domain with a blasticidin resistance gene; one encoding the MS2-p65-HSF1 fusion protein with a hygromycin resistance gene; and one encoding a target-specific 20 nt sgRNA fused to two MS2 RNA aptamers with a puromycin resistance gene. Following lentiviral transduction and genomic integration of the expression cassettes, the SAM components are stably expressed and assemble at the target locus within the proximal promoter region upstream of the TREM2 transcriptional start site, where VP64, p65, and HSF1 act cooperatively to recruit endogenous transcriptional machinery and drive sustained upregulation of endogenous TREM-2 expression. The use of nuclease-inactive dCas9 avoids the introduction of double-strand DNA breaks and preserves the native TREM2 genomic locus and regulatory architecture.
The lentiviral format offers several practical advantages: stable genomic integration supports heritable activation across cell divisions; high-titer particle preparations eliminate the need for in-house viral production; and compatibility with primary, non-dividing, and transfection-resistant cell types expands experimental accessibility. Successful transduction can be confirmed and enriched through triple antibiotic selection using puromycin, hygromycin, and blasticidin.
